Someone could explain me what is the difference between class and object in typescript.
class greeter{
Name: string;
Sayhello(){
console.log("hello")
}
}
Before I using this
var greeter = {
Name : "",
Sayhello: function sayhello(){
console.log("hello");
}
}
It is up to you. Both of these are valid and idiomatic TypeScript:
export class Greeter {
name: '';
sayHello() {
console.log('hello');
}
}
and
export const greeter = {
name : '',
sayHello: () => {
console.log('hello');
}
}
// if you need just the type of greeter for some reason
export type Greeter = typof greeter;
If you don't have a need for the class, don't use them.
But you may find benefits of classes if you want to:
If you have multiple instances, using classes or prototype constructor functions, allow you to share method implementations across all instances.
Even if you are in a purely functional paradigm, using prototype constructor functions or classes can be useful for creating monads.
If you only have one instance, and do not need for a constructor, an object is is probably fine.
export var greeter and get the explicit type bound to the literal object. What you can't do is have an abstract type, say another 'kind' of greeter that implements the greeter type.There are many differences. On a basic level, a class is an object that can be used to create other objects with a specific shape and functionality. It provides syntactic sugar for functionality that would be a lot more work to accomplish with plain objects and functions.
You should take some time to read about what classes are in the TypeScript Handbook because answering your question in detail would be equivalent to writing a few chapters of a book—especially when tailoring it for TypeScript.
